Have you tried the example program? Reading its source will likely give you a reasonable starting point.

Take a look here:

A few of us have used these and do work well with David Smart's library.

https://developer.mbed.org/components/RA8875-Based-Display/

They deliver quickly, I have ordered from them three times now with no problems.

I have the 8" version that's excellent.

You will need to order the RA8875 chip version with 4-wire SPI option and 'resistive' touch display, this is supported here.

3v or 5v supply option, however the Mbed may struggle to give enough current to power the display from the on board regulators with the larger displays. The 4.3" display needs approx. 200mA on the 5v option.

All the options can be changed by jumpers on the driver board.

Accepted Answer

Thanks for that I looked at it and I'm going to give it a go I'll let you know how I get on Thanks
